Things move slowly when you're dealing with big companies and major deals. We first caught wind of the deal between Panasonic and Sanyo back in December of 2009 and things have been moving slowly but surely.

Panasonic has dropped as much as $9.8 billion to make the deal go
through, as well as a similar arrangement that would allow Panasonic
Corp. full ownership of Panasonic Electric. Panasonic now owns 80
percent of Sanyo and expects a full takeover to be complete by March.

One of the prime assets that the folks at Panasonic are excited to
acquire is Sanyo's litium-ion battery tech that's used in both
electronics and cars. Sanyo also has a range of technologies in the
research and development phase that are said to be quite substantial,
making this a deal full of potential for Panasonic.
